Description

Technical Field

[0001] The present invention relates to the technical field of wave power generation, and in particular to a wind farm wave power generation device driven by potential energy. Background Art

[0002] As a renewable energy technology, wave power generation has important research and application value. The energy density of wave energy is relatively high, especially in the mid-latitude 30° to 40° area, where wave energy can reach 30 to 70kW / m, and even up to 100kW / m in some places. Wave energy is the most widely distributed renewable energy in the ocean and can become a source of energy for remote areas at sea. The basic principle of wave power generation is to capture the kinetic energy and potential energy of waves and convert them into electrical energy. The main conversion technologies include: oscillating water column type, oscillating float type, overpass type, duck type, raft type, etc. In the future, the research and development of wave power generation devices will integrate wave energy with other renewable energy sources (such as solar energy, wind energy, etc.) to form a multi-energy complementary system to improve the stability and reliability of energy supply. In the future, wave power generation technology is expected to make new breakthroughs in multi-degree-of-freedom array power generation, multi-energy complementary coupling power generation, and multi-functional integrated platform utilization.

[0003] Although the existing traditional oscillating float wave energy power generation devices have certain advantages, they also have some shortcomings. For example, the stability is insufficient: under severe sea conditions, the oscillating float device may experience large shaking and displacement, affecting its normal operation; high maintenance cost: the device operates in the marine environment and requires regular maintenance and inspection. Due to its remote location, maintenance work is difficult and costly. Traditional overriding wave energy power generation devices also have some shortcomings, such as low wave energy utilization: under certain sea conditions, wave energy cannot be effectively converted into electrical energy, resulting in low energy conversion efficiency; complex structure: overriding devices are usually composed of multiple parts such as sloped wave-generating surfaces, water reservoirs, guide vanes and outlet pipes. The structure is relatively complex, which increases the difficulty of construction and maintenance.

[0004] In addition, traditional wave energy power generation devices have single functions, low power generation efficiency, high construction and maintenance costs, and cannot be well integrated with other renewable energy sources. Wave energy power generation devices need to form a multifunctional complementary system to improve the stability and reliability of energy supply. Summary of the invention

Among them, the water intake device 4, the water storage device 5, the water discharge device 6, the water pumping device 7 and the connecting device are all connected to the floating body device and the potential energy generating device 1 in a circular array to form a whole. The connecting device is a two-way connector, a three-way connector and a one-way valve.

[0035] In this embodiment, the power generation device includes a total of 6 working units in a circular array. The 6 working units are connected and fixed by connecting equipment: a three-way connector 8 is connected between the water intake device 4 and the water storage device 5, a two-way connector 9 is provided between the water pumping device 7 and the potential energy generating device 1, a connecting and fixing rod 10, a floating device 11, a trapezoidal floating body 11-1 inside the floating device, a three-way connector 12 at the water discharge device, a two-way connector 13 at the water pumping device, and a water pumping pipe 14 are connected and fixed. The floating device is to fix the power generation device on the floating device to form a whole and most of it floats above the sea surface. The water pumping device 7 pumps water into the potential energy generating device 1.

[0036] The water intake device 4 includes a moving rod 4-5, a float 4-6, a water intake sheet 4-7 for water intake, a first water inlet pipe 4-1, and a second water inlet pipe 4-2. The water inlet of the water intake device is provided with a first valve 4-8, a second valve 4-9, a first water outlet pipe 4-3, a second water outlet pipe 4-4, and a third valve 4-10 and a fourth valve 4-11 at the water outlet of the water intake device. One-way check valves are installed inside the two water outlet pipes connected to the water outlet of the water intake device 4. The two water outlet pipes intersect in a horizontal position to form a single water outlet pipeline, and the connection is connected with a three-way connector. The first water outlet pipe 4-3 and the second water outlet pipe 4-4 are connected to the water inlet pipe 5-1 of the water storage device 5 in a horizontal position with a three-way connector 8.

[0037] In this embodiment, the water inlet and outlet in the water intake device 4 are symmetrically arranged, and the one-way switch valves arranged at the water inlet and the water outlet are composed. The water inlet and the one-way switch valve of the water inlet are arranged in the upper and lower symmetrical positions on the left side. The two water inlet pipes connected to the water inlet are deep below the sea surface, and the pipe mouths are wrapped with mesh to prevent debris from entering. The water outlet and the one-way switch valve of the water outlet are arranged in the upper and lower symmetrical positions on the right side. One-way check valves are installed inside the two water outlet pipes connected to the water outlet. The two water outlet pipes meet at a horizontal position to form a single water outlet pipe, and the connection is connected with a three-way connector.

[0038] The water storage device 5 has an inlet pipe 5-1 and an outlet pipe 5-2. The water storage device 5 is used to store water and transfer it to the water discharge device 6. The water storage device 5 is a hollow cylindrical tank body, with an inlet at the top connected to a single outlet pipe formed by the intersection of two outlet pipes of the water intake device, and an outlet pipe arranged at the bottom, and a one-way check valve installed at the outlet pipe.

[0039] The drain device 6 is a non-sealed can-shaped container, which is composed of a permanent magnet, a float 6-1, a float support plate 6-3, and a connecting rod 6-2 connecting a valve located below the water inlet of the drain device and the bottom of the float. The valve is initially open, and the float is initially stationary on the float support plate 6-3. The drain device 6 has an edge opening 6-5.

[0040] The permanent magnet is located at the top surface of the inner part of the float, and the tank top of the drainage device is made of magnetic metal. When not affected by buoyancy, the total weight of the float, permanent magnet, connecting rod, and valve is greater than the magnetic force when the micro permanent magnet and the inner surface of the tank top are combined. The float support plate is annular, and the diameter of the middle hollow circle part is smaller than the maximum diameter of the float. The float support plate 6-3 is fixedly connected to the inside of the drainage device 6. The external water inlet of the drainage device is connected to the outlet pipe at the bottom of the water storage device 5. The drainage device 6 is a non-sealed can-shaped container, that is, a hole 6-5 is opened around the container, the diameter of the opening 6-5 is smaller than the diameter of the water inlet of the container, the position of the opening 6-5 is distributed below and above the float support plate, and the total area of ​​all the openings is smaller than the area of ​​the container water inlet.

[0041] A section of water outlet pipe 15 is connected between the water discharge device 6 and the water pumping device 7. The water pumping device 7 has a valve 7-1 and a water pumping port 7-2 inside, and a water pumping pipe 14 is connected to the water pumping port 7-2 outside.

[0042] The pressure tank of the water pumping device has air density inside. A one-way valve is installed at the tank mouth of the pressure tank. The open position of the valve is open toward the tank, and the initial state of the valve is closed. The tank mouth of the water pumping device is connected to the second section of the water outlet pipe with a two-way connector. There is a water outlet near the tank mouth, and the water outlet is connected to the pump water pipe outside.

[0043] The potential energy generating device is composed of a hollow truncated cone with a large upper bottom surface and a small lower bottom surface, and without upper and lower bottom surfaces, and a turbine generator and a pipeline combined with the lower bottom surface of the truncated cone. The outer diameter of the pipeline is consistent with the diameter of the lower bottom surface of the truncated cone and is combined at the same horizontal plane as the lower bottom surface of the truncated cone. The turbine generator is located inside the pipeline, and the pipeline is used to protect the turbine generator. The upper circumferential array of the truncated cone container of the potential energy generating device has a water inlet connected to a pump pipe connected to the water outlet of the pumping device. The turbine generator at the bottom of the potential energy generating device is used to convert the potential energy of the water in the truncated cone into mechanical energy and then into electrical energy.

[0044] The potential energy generating device 1 is connected to the pumping device 7 via a pumping pipe 14. The potential energy generating device 1 is externally connected to the light energy generating device 2 to absorb light energy, and also includes a turbine generator 3 for generating electricity. A first one-way valve 16-1 is provided on the first water outlet pipe 4-3, a second one-way valve 16-2 is provided on the second water outlet pipe 4-4, and a third one-way check valve 16-3 is provided on the water outlet pipe 5-2 of the water storage device 5.

[0045] The six working units of the entire circular array are connected and fixed with a floating device to increase the power generation. The power generation device is located in the sea area between the wind turbines of the wind farm, and the stability is improved by semi-tensioned connection with the surrounding wind turbine bases.

[0046] like Figure 5 , Figure 7 As shown, the water intake device 4 has a water intake piece 4-7 that fits tightly with the inside of the water intake device, and a moving rod 4-5 that fits tightly with the bottom opening of the container. The waves drive the float 4-6 to move up and down, and the moving rod 4-5 is connected to the float 4-6 and the water intake piece 4-7. The up and down movement of the float 4-6 drives the water intake piece 4-7 to move up and down. Since the inside of the device is airtight, when the float 4-6 drives the water intake piece 4-7 to move upward under the action of waves, the pressure below the water intake piece of the device container decreases, and the second valve 4-9 at the lower water inlet of the device opens under the action of pressure, and seawater enters the space below the water intake piece 4-7 of the device through the second water inlet pipe 4-2. The device does not take in water from the second water outlet pipe 4-4 because the fourth valve 4-11 at the lower water outlet is closed under the action of pressure at this time and the second one-way check valve 16-2 is provided inside the second water outlet pipe 4-4. At this time, the pressure above the water intake plate of the device container increases, the first valve 4-8 at the upper water inlet is closed under the pressure, the third valve 4-10 at the upper water outlet is opened under the pressure, and water flows out from the first outlet pipe 4-3. Since the device is internally sealed, when the float 4-6 drives the water intake plate 4-7 to move downward under the action of waves, the pressure above the water intake plate of the device container decreases, the first valve 4-8 at the upper water inlet of the device is opened under the pressure, and seawater enters the space above the water intake plate 4-7 of the device from the first water inlet pipe 4-1. The device does not take in water from the first outlet pipe 4-3 because the upper third water outlet valve 4-10 is closed under the pressure and the first one-way check valve 16-1 is provided inside the upper first outlet pipe 4-3. At this time, the pressure below the water intake plate of the device container increases, the second valve 4-9 at the lower water inlet is closed under the action of pressure, the fourth valve 4-11 at the lower water outlet is opened, and water flows out from the lower second water outlet pipe 4-4.

[0047] The drain device 6 and the pump device 7 are as shown in the attached Figure 5 , Figure 8 , Fig. 9A three-way connector is connected between the water outlet pipe 5-2 of the water storage device 5 and the water outlet of the water discharge device 6 and the water outlet pipe 15. The water outlet pipe 15 and the opening of the water pump device 7 are connected via a two-way connector 13.

[0048] Initial conditions: (1) The sum of the masses of the permanent magnet 6-6, the float 6-1, the connecting rod 6-2 and the valve 6-4 inside the drainage device 6 is greater than the magnetic force when the micro permanent magnet 6-6 is in contact with the top surface inside the drainage device 6; (2) The total area of ​​the holes 6-5 on the drainage device 6 is smaller than the container mouth area of ​​the container; (3) H1 and H2 are equal in size; Fourth, the interior of the pumping device 7 has air density and is sealed, and the valve 7-1 of the device is in a closed state in the initial state.

[0049] The potential energy driven wind farm wave energy power generation method of the present invention comprises the following steps:

[0050] (1) When the waves drive the water intake plate 4-7 upward through the float 4-6, the pressure below the water intake plate decreases, the second valve 4-9 at the water inlet opens, and seawater enters the space below the water intake plate 4-7 through the second water inlet pipe 4-2; at this time, the pressure above the water intake plate increases, the first valve 4-8 at the first water inlet closes under the pressure, the third valve 4-10 at the upper water outlet opens under the pressure, and water flows out from the upper first water outlet pipe 4-3. When the waves drive the water intake plate 4-7 downward through the float 4-6, the pressure above the water intake plate decreases, the first valve 4-8 at the upper water inlet of the device opens under the pressure, and seawater enters the space above the water intake plate 4-7 from the first water inlet pipe 4-1. At this time, the pressure below the water intake plate increases, the second valve 4-9 at the lower water inlet closes under the pressure, the fourth valve 4-11 at the lower water outlet opens, and water flows into the water storage device 5 from the second water outlet pipe 4-4;

[0051] (2) The water in the outlet pipe 5-2 of the water storage device 5 enters the water discharge device 6. The rising water level drives the float 6-1 to rise. When the sum of the gravity of the permanent magnet 6-6, the float 6-1, the connecting rod 6-2, and the valve 6-4 minus the buoyancy is less than the magnetic force when the micro permanent magnet 6-6 fits with the internal top surface of the water discharge device 6, the permanent magnet 6-6 fits with the internal top surface of the water discharge device 6 under the action of the magnetic force. Since H1 and H2 are equal, the valve 6-4 fits with the opening of the water discharge device 6. At this time, the flow direction and velocity of the water suddenly change. The pressure fluctuation caused by the inertia of the fluid causes the water pressure inside the outlet pipes 5-2 and 15 to surge. While the pressure surges, it also ensures that the valve 6-4 of the water discharge device 6 is not opened due to gravity. And the presence of the third one-way check valve 16-3 ensures that the water does not flow back.

[0052] (3) The valve 7-1 of the pumping device 7 opens when the gravity is less than the pressure of the water in the lower pipe. Since the pumping device 7 is sealed inside and has air density, the water compresses the air above. At this time, the internal pressure of the pumping device 7 surges and presses the water in the device into the pumping pipe 14 connected to the pumping port 7-2. After the water in the device is pressed into the pumping pipe 14, the water pressure in the device and the lower water pipe decays rapidly. At this time, since the internal pressure of the pumping device 7 and the gravity of the valve 7-1 of the pumping device are greater than the pressure in the lower water pipe, the valve 7-1 of the pumping device is closed again. The water level of the draining device 6 is lowered due to the drainage of the small hole 6-5 of the draining device, the buoyancy of the float 6-1 is reduced, and the water pressure in the lower water pipe is reduced. The sum of the weights of the permanent magnet 6-6, the float 6-1, the connecting rod 6-2, and the valve 6-4 is greater than the magnetic force when the micro permanent magnet 6-6 is attached to the top surface of the draining device 6, so that the valve 6-4 opens again.

[0053] (4) The potential energy generating device 1 is connected to the water pumping device 7 via the water pumping pipe 14 to pump water into the container of the potential energy generating device 1. The potential energy generating device 1 is externally connected to the light energy generating device 2 to absorb light energy for power generation. The turbine generator 3 inside the potential energy generating device 1 converts the potential energy of water into electrical energy for power generation.

[0054] The light energy generating device is a hemispherical grid frame as a whole, and each grid is used to lay photovoltaic panels. The diameter of this hemispherical grid frame is the same as the diameter of the upper bottom surface of the hollow truncated cone of the potential energy generating device, and the bottom of the hemispherical grid frame is connected to the upper bottom surface of the hollow truncated cone container. The hemispherical network frame not only provides light energy generation, but also increases the amount of water in the truncated cone during storms or rain at sea, increasing the power generation.

[0055] The floating device is composed of a circular ring-shaped floating body and a trapezoidal floating body inside the circumferential array, which are connected to a water intake device, a water storage device, a water discharge device, a water pumping device, a connection device, and a potential energy generating device through fixed rods to form a whole, so that the whole floats on the sea surface. The circular ring-shaped floating body on the edge of the floating device is not only used as a connection and fixing device, but also as a maintenance platform.
